Sharp Edge (Cumbria) is the premier
sharpening service for all users of catering and food preparation knives.

Most plain knives are
sharpened using the Tru-Hone system (an American
sharpening machine which is portable and clean to use).

The machine has two counter
rotating grinding wheels, sharpening both sides of the blade at the same time,
which are adjustable for grinding angle and for speed. A three stage process is
used for every knife. The first stage is to grind the knife until it is sharp, the second stage then strengthens the actual cutting
edge, whilst the third stage hones the blade using a slower speed. Heavy
chopping knives and meat cleavers use the same process but the blade angle is
different.

Knives which have suffered an
'accident' can be reshaped and then sharpened. This needs to be done back at
base using a belt system or on a bench grinder.
